SPRINKLER ALARM DEVICE.

Specification of Letters Patent.

To all whom it may'cmwem:

Be it known that I, Evanmr L. Tnoiirson, a citizen of the United States, and a resident of Dover, in the county of Morris and State of New Jersey, have made new and useful Inventions Relatin to Sprinkier Alarm Devices, of which the ollowing is a specification, taken in connection with the accompanying drawings, forming part of the same.

This invention relates to sprinkler alarm devices and relates' especially to audible alarm signals and means for operating the same from s rinkler alarm systems in the event. of fire y means of water compreing blast devices and means to operate the alarm which may be in the form of a whistle from the blast thus created.

In the accompanying drawingA showing somewhat diagrammatically an illustrative embodiment of this invention, 1 is the supply pipe connected with the casing 2 on the upper side of which the supply pipe tion 'i' may connect with the regular distributing system. The casing 2 may be provided with any suitable emergency device to operate in the event of tire and the check valve 3 may be used for this purpose when peroperly guided in the casing which may one by a suitable stem, such as 4. The packing 5 indicated on this valve closes the alarm passage 6 connecting!` with the aperture .37 and pipe 8 leading to the air' coin ressing apparatus or blast device, whic may be in the form of a suitable injector as indicated. This injector may comprise the jet nozzle 9 coperating with a suitable throat 10 so as to draw air or other blast medium through the protecting screen 11 and force the same under suitable pressure through the discharge 12, 13 into a suitable separator. This separator 18 may comprise an `desired number of baie plates 15 supportedfrcm the bottom 14 of the separator and 'coperating dependingv bullies 16 supported from the upper wall of this water chamber, a number of blast. escape openings 17 being rovided so thatthe air or other blast m ium rises and collects within the up r portion of the separator. This air may led through the pipe 19 of any desired length or shape to operate an electrical or other :darm mechanism and may lead to an audible alarm in the form of a whistle 20 or otherwise located at any convenient point so as to continuously operate the Sallie as long as the water is flowing through the system under emergent-v cmiditions. y

It is usually desirable to have a water valve in connection willi the separator and the valve may be mounted adjacent the discharge o ieiiing from the separator so as to control tie same and prevent the escape of water therethrough. The valve 23 may for this purpose be mounted on the float 21 -movablv supported in the separator, for example y pivoting the same about the pin 24 and arranging the tiexible connect-or 22 in connection therewith. On the rise of water this float Would, ofcourse, rise and close the discharge opening so that this water valve would eectually prevent any water from passing to the alarm until the water fell sutliciently to allow the float to descend and open the valve by its weight.

Any desired means may be used for maintaining iii the separator the blast pressure roper for operating the alarm. This may e effected by arranging a suitable throttlinfr device on the water discharge pipe 25, this device being, if desired, in the form of a valve pivoted about the pin 28 so as to con- 'trol the opening 26 and forced down upon its seat by the spring 30 actin on the valve arm 29. The intensity of this spring action may be readily adjusted by any desired means, such as the set screw 31 operating in the lng 32 so that by this means any desired blast pressure may be maintained iu the se iarator and when the pressure therein ex s this amount the throttling valve will open and allow the discharge from the separator to pass out of the spout 34. Of course, if desired, a fgravit-y throttlng device may be employed or this saine purpose by connectiner a suitable uptake 35 to thc discharge 25, this uptake being carried up to the desired vertical height and then emptying into a drain 36 or the like.

Having described this invention in connection with an illustrative embodiment thereof, to the details of which disclosure it is not, of course, to be limited, what is claimed as new and what is desired to be secured by Letters Patent is set forth in the appended claims.

l. In sprinkler alarm devices, a supply pipe connected to n distributing system, a

check valve in said supply pipo, there being 110 an alarm assage controlled by said check valve to allow water to pass therethroufh on the emergency o eration of said sprink er system, a blast in]ector connected to said alarm pnssa'e and operated by passing llnld therethrough, a separator provided with a water valve and throttlnv device connected to said injector and nn a arm whistle connected to said separator and operated by the airblast therefrom.

2. ln sprinkler alarm devices, a supply pipe to be connected with a distributing system, an emergency device in said supply pipe and provided with al1 alarm passage a Water blast device and se arator connecte to said alarm passage an operated by the `rater passing therethrough and an audible alarm connected with said separator and operated by the blast therefrom.

3. In sprinkler alarm devices, a water blast in'ector to be connected with an emergency evice and operated by water therefrom, a separator connected to said device and having a water valve and throttling and alarm mechanism com rising a whistle device connected therewith and an alarm connected to said separator and operated by the blast therefrom.

4. In sprinkler alarm devices, a. water blastinjector to be connected to and o rated by an emergency device in a s ri er system, a separator connected to said blast evce to separate the blast from the water discharged therefrom and to be connected with an audible alarm and operate the same by the blast from said se artor.

5. In sprinkler alarm evices, a blast device to be connected with an emergency de rice of a sprinkler system and operated by the liquid discharged therefrom, and a l separator connected with said blast device i to separate the blast from said liquid and to be connected with and operate an alarm by said blast.

G. In sprinkler alarm devices, a blastdevice to be connected with a sprinkler system and operated by Huid discharged therefrom to produce a blast during the irregular operation of said system and an alarm connected with said blast device and operated by the blast passing from said device toward said alarm.

7. In sprinkler alarmdevices, an in`ector blast device to be connected with a sprinkler system and operated by (luid discharged t lerefrom to produce a blast during the emergency7 condition of said svstem and alarm mechanism to be connect with said blast device and operated by the blast ass ing from said blast device toward said arm mechanism during the emergency condition of said system.

8. In sprinkler alarm devices, a blast device to be connected with an emergency device in a sprinkler system and operated by llnid discharged therefrom to produce a blast to he connected `with said last device and operated by the blast passing from said blast device toward said alarm mechanism.

9. In sprinkler alarm devices, a blast device to he connected with a. sprinkler system and operated by iinid discharged therefrom to produce a blast during the irregular operation of said system and means to be connected with an alarm and operate the same by the blast passing from said blast device toward said alarm.
